Ordered some Merv 11 filters that whistled when in use. Filled out a review because I wasn’t happy but didn’t expect to hear anything. Within the day, Matthew from customer service reached out and right away offered to exchange to a Merv8 and I just received them today and it fixed my issue. Great customer service!!! Will do business in the future. I withdraw my previous 2 star review. Thank you! Refreshing to get great customer service!

Thank you so much for your quick and kind response to my size exchange request after I accidentally ordered the wrong size. I was also truly touched that you told me I didn’t need to send the original filter back. I really appreciate your excellent customer service.

Excellent Costumer Service by RAY!
Our September 2025 order arrived in a timely manner and sat safely in our garage until we finished using a previous order . We discovered in May 2026 that the filter dimensions were .5” smaller than we expected for 20x25x1 size ordered. (Apparently, there are some industry differences with exact size requirements..). Emailed FilterKing 8months after the purchase, hoping for an opportunity to return the filters, but fully expecting to be stuck with them so long after the purchase. RAY at FilterKing responded to my email the same day it was sent. He not only offered to replace the filters, he said we could donate the existing box instead of having to return them. His customer service was above and beyond what we expected, and we couldn’t be more pleased. What a great experience to deal with a company who does the right thing by their customer. BUY FILTERKING FILTERS!

Thank you so much for taking the time to share this. We’re really glad Ray was able to help and make the situation right for you. Filter sizing can definitely be confusing, especially when nominal and exact dimensions differ, so we’re happy we could step in with a solution that worked for you. It means a lot to hear that the experience exceeded your expectations. We truly appreciate your support and your kind words, and we’ll be sure to share this with Ray. Thank you again. Filter King.

Repeat Customer
This is the third or forth time I have ordered filters from Filter King. It is always an easy transaction and very competitive pricing. This last time I accidentally ordered the wrong size filters and only realized after I had paid and after regular business hours. I sent customer service an email and the next morning I had a reply from Ray that he had already corrected the order. Fantastic service!
